In addition to winning the Supreme Champion award for its Wensleydale, the company also picked up a gold medal in the Wensleydale class one of four gold, seven silver and three bronze awards it won in the competition, which took place at the Royal Bath and West Show.
The awards were the result of dedication and hard work, said Belton MD Justin Beckett. "With such stiff competition, we are so proud our Wensleydale has been deemed the best."
